X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e567b34f0d67a184ee17013f5262122fcd1380c0;p=mesa.git svga: Clamp advertised PIPE_SHADER_CAP_MAX_TEMPS to SVGA3D_TEMPREG_MAX. Some backends may advertise more temps than SVGA3D_TEMPREG_MAX, but the driver is hardwired to only support up to the value defined by SVGA3D_TEMPREG_MAX, so clamp to it.
